Imagine diving deep into the ocean surrounded on all sides by brightly colored corals, and exploring the majestic marine life living deep beyond the beach. Often your excursions will take you to explore in conditions that are less than ideal for seeing the world around you, like while diving to ancient shipwrecks, or seeing new species in murky waters. In these conditions, having the best scuba diving light on the market as an additional light source will allow you to see everything clearly and make your dive even more magical and memorable for years to come.
A light suitable for diving goes far beyond the flashlight found in your utility drawer. It has to be waterproof, durable enough to handle depths, have a long-lasting battery life, and have a powerful beam illumination. You should also consider the type of bulb used as the light source, and the materials used for convenience and ease in maintenance.
Here we’ve gathered an informative guide to help you choose the best light for your diving adventures, which will keep you exploring the depths for many dives to come. Keep reading for a breakdown of things to look for in your dive light purchase, and some of the highest rated lights on the market today.
What to Look for in Scuba Diving Lights
Before you invest in a dive light for your next scuba trip, it helps to know the different features to better understand which lights will best suit your scuba diving needs. From features like dive depth limits, battery types, beam type, maintenance and more, there’s a light on the market for every scuba lover. Let’s get started with several key features to check for when purchasing lights for your deep blue adventures.
Basic Dive Light Features
Every dive light, no matter how basic design or style, should contain the following core features:
- A waterproof casing around the device and the ability to withstand water pressure in diving depths.
- A user friendly switch that can be used underwater even when a diver is wearing gloves.
- A secure wrist clip to ensure that even if the diver accidentally lets go, they don’t lose their light.
Dive Light Battery Type
During your dive, your light will likely run on batteries that are either rechargeable or disposable. The question is- which is better for you? The rechargeable batteries require a bit more initial investment, but are a better option for frequent divers as they can be reused time and time again. If you go scuba diving infrequently, like once a year, disposable batteries may be the better way to go. The type of battery you use in your lights will also affect how long your light will run for, and how bright the beam is.
- Alkaline Batteries: These batteries are easy to find just about anywhere in the world and are budget-friendly, especially when on the go. However, their battery life is short and their performance is not as good as some of the better battery options available today.
- Lithium Batteries: Lithium batteries are actually recyclable and offer better battery performance than the alkaline ones. However, they can be quite expensive as an upfront cost.
Batteries Suitable for the Travel Diver
If you’re a diver on the go, you’ll need to consider more than just the battery performance and price when purchasing your dive lights:
- Lithium batteries, although convenient, long-lasting and recyclable, are generally not allowed on airplanes and are therefore not suitable for typical travel divers. If, however, you’re sticking to land travel, these batteries are a great option.
- Travelers may not always have ready access to charging ports, making it difficult to charge their rechargeable batteries, leaving them to purchase disposable batteries on the go. Disposable batteries, in this case, may be a better option.
Wide Beam vs. Tight Beam Dive Light
There’s a difference in beam type when looking at dive lights on the market, and which you should choose depends on your goals while diving. Wide beam lights illuminate a large area underwater and are ideal for use in calm, clear waters. These lights are also the preferred option for nighttime diving since they provide a wider area of visibility.
For diving in water with significantly low visibility, like that of dark or murky waters, a tight beam light provides better visibility underwater because the sharper light cuts through the haze. The tight beam is also ideal if you’re exploring shipwrecks with small corners and tiny spaces.
Choose a beam style that suits the places you’ll be diving to, and the amount of light that will be available while exploring there.
Type of Bulb
There are 3 key types of bulbs to choose from when investing in quality dive lights:
- Halogen or Xenon Bulbs: These bulbs have a very short battery life, but their light illuminates natural light, which gives your dive an interesting new flare. They also come in handy when you plan on recording your dive.
- LED Bulbs: LED bulbs produce a brighter light compared to other types of bulbs used in diving lights, and they’re well known for lasting a long time while underwater. However, this type of light has a bluish tinge, which can feel a bit eerie, especially at night. It’s something to consider when deciding how you want to experience the deep blue.
- HID Bulbs: HID bulbs have become relatively redundant and have been taken over by their modern substitute, the LED bulb.
There are two main ways for a diver to carry a dive light around underwater:
- Dive lights may be carried in a sealed unit with a handle and a wrist clip for ease in carrying, and to protect the diver from losing the light when dropped.
- With the canister-type dive lights, on the other hand, the battery is sealed in a canister that is connected to a headlamp through a sealed wire. These are typically used by more technical divers such as cave divers.
Dive Light Seal
The seal on your dive light is what protects the important components of the light from water and the elements while diving underwater. A poor quality device can, and likely will leak water, potentially ruining your dive trip. Prepare ahead of time, invest in well-built device and dive in to explore the beautiful world below the surface.The most popular seal for a dive light is the use of O-rings, which keeps the interior components dry and protected from water. Some newer models are completely sealed and use rechargeable batteries that can be recharged magnetically.
Keeping a Backup
It is recommended by all the experts that divers have a backup dive light in case the main one gets lost or runs out of batteries, etc. Backup lights are usually smaller and more compact, so that they can be carried around conveniently and tucked away in gear when needed.
Secondary (backup) lights are usually small enough to be stored in a BCD pocket or clipped on with a carbine. Make sure you remember to pack your backup on every trip diving, when you need it most you’ll be grateful that it’s there!
With the proper care, your dive light can last you for many dives and years to come:
- Remember before every dive to always check if the light and batteries work properly before your dive. Understanding your equipment and ensuring it’s in functioning condition is essential to both safety and convenience while underwater.
- Never leave your light sitting on the sand or let it brush against the ocean floor. A few grains of sand can damage your light permanently, adding additional costs in having to buy a new one.
- After your dive adventure, rinse your light thoroughly to get rid of the salty water and any other grit and dirt. Practicing proper maintenance on all of your dive gear is crucial for its longevity.
- Store your dive light only after it is 100% dry in a safe place with other gear. Make sure to remove the batteries before you store it, and charge them in preparation for your next dive.

However, the light becomes quite heavy after inserting the battery which can become a hassle to carry around, especially if you’re exploring in tight spaces or trying to film your dive.
